Python. List.

Question

Explain me the difference between these two codes, please:

list_1 = [x for x in range(4)]
list_2 = list_1
list_1 += [7]
print(list_1 == list_2) # -> True

list_3 = [x for x in range(4)]
list_4 = list_3
list_3 = list_3 + [7]
print(list_3 == list_4) # -> False

Obviously, the only difference is: list_3 = list_3 + [7] and list_1 += [7], but how does it affect the outcome?
